11. A device for diffusing volatile substances comprising:
a housing containing volatile substances;
a capillary element having a central axis that defines an axial direction relative to the device, the capillary element extending axially from the housing to a distal end of the capillary element outside the housing;
a piezoelectric element at the distal end of the capillary element; and
an elastic element connected between the housing and the piezoelectric element, the elastic element extending axially from a connection of the elastic element to the housing to a connection of the elastic element to the piezoelectric element, the elastic element extending radially away from the connection of the elastic element to the housing and radially away from the central axis of the capillary element as the elastic element extends axially from the connection of the elastic element to the housing to a hole in the elastic element that is spaced axially from the housing, and
the piezoelectric element is mounted in the hole.
